<p>Cemento-ossifying fibroma (COF) is a benign fibro-osseous lesion commonly seen in the head and neck regions. It is considered as a benign, locally aggressive neoplasm that requires surgical excision. COF has traditionally been considered to be slow growing. We report a case of 11 year-old girl who presented to the ENT Department of our hospital with 7 months history of nasal obstruction, proptosis and headache. Computed Tomography scan images showed a mass in the right nasal cavity. This case is notable because involvement of the sphenoid sinus is rare. </p>

Parapharyngeal space is one of the potential space for neoplasms and infections and represent less than 1% tumours of all head and neck tumours. Pleomorphic adenoma occurrence in para pharyngeal space is rare presentation. The anatomy of the parapharyngeal space is complex. The complex anatomy and wide variety of pathology make the management of these tumours very challenging.
